Of course, in addition to choosing the brand of the hammer bit, we should also find ways to reduce the cost from the use of the hammer bit. Let’s take a look at these methods and give you a reference~
- The joint of the hammer and the joint of the drill pipe are all right-handed threads. During use, we should always keep the right-handed twist.
- When drilling a hole, the minimum impact and driving force should be selected, so that the DTH bit can enter the rock layer smoothly. The driving force of rock drilling should change with the weight of the DTH drilling tool. The weights have to match.
- When changing the rod, cover the two ends of the drill pipe that has been removed to prevent the stone ballast from entering the drill pipe and finally causing the wear of the hammer.
- When the hammer is in use, it often encounters the situation of stuck drill. At this time, don’t panic and reverse, and you should force the bottom to remove the ballast in time.
- During use, the wear of the drill pipe of the hammer should also be timely understood. If it becomes thinner or cracked, it should be replaced in time to avoid breaking and falling into the hole, which is not worth the loss.
- The hammer needs reasonable lubrication, which is also the key to prolong the service life of the hammer. And doing these details can extend the life of the hammer bit by 50%.
